Waste Heat Boiler. Exiting the WHB, the cooled stream achieves the first condenser where its temperature lowers to 180°C. After each catalytic reactor (two or three, depending on the SRU layout) there is a sulfur condenser operating at about 160°C. In these unit operations, low pressure (LP) steam is produced (3 to 10 bar).

Sulphidation corrosion and thermal cycling in Claus waste heat boilers (WHB) are the two leading causes of unexpected failures that result in unscheduled shutdowns of sulphur recovery units (SRU). Sulphidation corrosion is caused by two main factors: high temperatures, typically exceeding 650°F (343°C), and hydrogen sulphide (H2S).
